Scientists have found evidence that Neanderthals and humans interbred more recently than previously thought, with some research suggesting this occurred within the past 50,000 years, although the exact timing is not certain. The discovery sheds new light on the procreation patterns and interactions between the two species. The findings are based on studies of dna, skull research, and other evidence, but some details, such as the specifics of the interbreeding, are still unclear.
